∙ 1 ∙ CARDIO KILLS MUSCLE
This is the main ‘gym bro’ myth that still persists, but it couldn’t be further from the truth. Regular cardio will, in fact, strengthen your ability to build muscle. By increasing blood flow, cardio makes it easier for your body to repair muscle damage, helping you feel less sore the next time you work out, thereby speeding up progress.
∙ 2 ∙ CARDIO BURNS FAT
Cardio burns calories, not fat. Fat loss comes down to calorie management, not just the amount of aerobic exercise you do. If your end goal is to lower body fat, monitor your diet so that you are in a caloric deficit. Be aware, though, that only doing cardio and not monitoring your food can burn up muscle tissue. As with any element of training, the result cannot be achieved without tailoring your diet accordingly.
